AUTOMATIC SNOW CLEANING AND MELTING MACHINE.

Application filed March 22, 1927. Serial No. 177,431.

This invention relates to snowremoving and melting machinesnlsed by street cleaning departments and the' like. Theinvention has for an object the prov sion of an improved snow removing and melting machine of novel construction and arrangement of parts. v

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which .the various novel features of the invention are more particularly set forth.

Fig.1 of the drawings, is a top plan v ew ofmy improved snow removing and melting machine.

Fig.2 is a side elevational view thereof.

Fig. 3 is a front elevational view thereof.

Fig. 4 is a transverse sectional view taken on the line 44 of Fig. 2.

Fig. 5 is an enlarged detail sectional view of the conveyor driving mechanism, as used in combination .with my improved machine. Fig. 6 is a detail sectional view of the mechanism. employed to operate. the upper plow member, as used in combination with my improved machine.

As here embodied my improved snow removing and melting machine comprises a self-propelled vehicle, similar to a motor truck, such as generally used for commercial purposes, preferably propelled by an. internal combustion engine, or the like, and provided with the usual transmission, drive shaft, front and rear axles, and a steering gear,. wh-ich-comprise the usual commercial vehicle chassis in common use.

The above mentioned chassis has mounted thereon, a cab. 10, such as commonly used to accommodate and protect the operator from the elements of the Weather. The said chassis has also mounted thereon a body 1.2, hereinafter fully set forth and explained in detaiL' The slice bar 13, extends across the extreme front of my improved machine, and is provided with downwardly depending elements' 14, adapted ,to cut or loosen the snow.

The slice bar 13 is attached to the support 15 extending from the front of my improved machine.

The plough member 16, extends across the front of my improved machine, and is positioned adjacent to and directly at the rear of the slice bar 13, and is adapted to lough,

gated aperture in the guide 21, attached to the said cab 10. The operating rod 20 is provided with a handle element 22. The expansion spring 23, is positioned on the operating rod 20, and is superimposed between the guide 21 and the collar 24, attached to the operating rod 20, so as to nor- -mally hold the upper plough member 17, in

a vertical position, or in line with the plough member 16. The above described construction is such as will permit the upper plough member 17 to be pivotally tilted, or hinged, backwards, so as to come in contact with the snow,'which may be deflected or thrown above the plough member 17, articularly when comparatively heavy dri ts of snow are encountered. It should'be understood that the springs 23 are adapted to urge the upper plow section 17 to its forward position after the same has been rotated rearwardly by retract-ion of the handles 22 for throwing the snow accumulated above the lower plow section 16in advance of the machine where it may be again picked up and directed to the buckets hereinafter described. The conveyors 25, comprising a plurality of link members, so as to provide endless flexible chains, have attached thereto buckets 26. The conveyors 25 are extended over the sprockets 27 attached to the shafts 28, rotatively supported by the above mentioned chassis of my improved machine. The con- "veyors 25 are extended over the sprockets 29, rot-atively mounted on the shafts 30, attached to the above mentioned my improved machine.

attached to the said sprocket 29, and over the sprocket 32 attached to the shaft 33, rotatively supported in the said body 12. The belt 34, of endless flexible construction, is

The chain-31 is extended over a sprocket body 12 of extehded over the ro1ler 35, rotatively mounted in the said body 12, and over the roller 36, mounted on the shaft 33.

Referring in particular to Fig. 5 of the accompanying drawings, the drive shaft 37, connected, as at 38, by a universal joint or the like, to the transmission 39, is adapted to rotate the rear wheels of the above mentioned chassis, the latter described elements being those of common construction, as hereinbefore set forth.

The drive shaft 37, has attached thereto, a gear 40, meshing with a gear 41, attached to the shaft 42, rotatively mounted in the case 43. The clutch member 44 is attached to the shaft 42. The clutch member 45, adapted to slidably engage the said clutch member 44, is attached to the tubular member 46, slidably positioned on the shaft 42. The tubular member 46 has attached thereto, at its extended extremity, a bevel pinion 47. The operating lever 48, provided with a handle element 49, is pivotally attached,

-. as at 49', to the transmission 39, and has pivotally attached thereto, as at 50, a rod 51, pivotally connected to the lever 52, attached to the pin 53, rotatively mounted in the said case 43. The pin 53, has attached thereto a lever 54, adapted to engage the collar element 55 of the said clutch member 45. It being understood that the handle element 49 of the operating lever 48, is conveniently located as respecting the operator of my im proved machine. The above described construction is such as will permit the lever 48, when pushed or forced forward to engage the clutch members 44 and 45, so as to rotate the bevel pinion 47, when my improved machine is in operation, i. e., when the drive shaft 17 is rotated. It will be understood that the said bevel gear 47, will thus be slidably engaged with a suitable bevel gear attached to the shaft 56, so as to rotate the sprockets 57 and the chain 58, extended over the said sprockets 57 and over a sprocket attached to the said shaft 28, so as to drive the conveyor 25, which will permit the buckets 26 attached thereto, to convey the snow from the plough member 16, which will be forced through the openings 58 formed in the plough members 16, directly in front of the buckets 26, so that the snow thus conveyed will fall upon the belt 34. which will be driven by the above described mechanism, attached thereto and to the conveyor, so as to convey the snow over the heater 59. v

The heater 59, is adapted to melt the snow brought in contact therewith, and comprises preferably burners of the fuel oil tvpe, which are supplied with fuel oil carried in the tanks 60, attached to the said body 12. The tanks 60 have connected thereto pipes 61, provided with the usual shut off valves 62, the pipes 60 being connected to the burners 59. The pipes 63, extend the entire length of the body 12, and are positioned below the burners 59 and the belt.34. The pipes 63 are connected to the exhaust pipe of the internal combustion engine, used to propel my improved machine, so as to permit the hot exhaust gases from the internal combustion engine to heat the snow, so as to assist in the melting of the snow.

The body 12, is provided with a tank member 64, positioned below the burners 59, and is adapted to hold the melted snow, which may be released therefrom when desired, by opening the valve 65. 1

It will be understood that the above referred to body 12, may be of suitable design and construction so as to accommodate the various elements mounted therein and attached thereto, substantially of the 0 en body type, provided with sides and on s, being open at the top.

While I have above described the preferred form, construction and arrangement of the several elements employed, it will be understood that the device is, nevertheless, susceptible of considerable modification therein, and I therefore reserve the privilege of resorting to all such changes as may be fairly embodied within the spirit and scope of the invention as claimed.

Having thus described my invention, what I claim as new and desire to protect by Letters Patent of the United States is as fol lows: I

1. A device'of the class described comprising a lower plow member mounted in advance of a vehicle, an upper plow section pivotally attached to said lower plow member, operating rods attached to said upper plow section and disposed at their rear ends in the cab of said vehicle adapted to be manipulated for changing the angular position of said upper plow section relative to the lower plow section, and springs mounted on said operating rods adapted to urge the same to their forward position for rotating said upper plow section forwardly to dislodge snow accumulated above said lower plow section.

2. A device of the class described, comprising a lower plow member mounted in advance of a vehicle, an upper plow section pivotally attached to the said lower plow member, operating rods attached to the said upper plow section and disposed at their rear ends in the cab of said vehicle and arranged for manipulation for changing the angular position of the said upper plow section relative to the lower plow section to dislodge snow accumulated above said lower plow.

In testimony whereof I have afiixed my signature.
